Though the Instrument Payload and Nadir Viewing Platform are being safely stored at the Space Station Processing Facility at NASA’s Kennedy Space Center, the Mission Operations and Ground System teams at NASA’s Langley Research Center are keeping busy making sure they are ready for commissioning and operations once SAGE III is installed on the space station later this year. The team at LaRC, along with the Payload Operations Integration Center at NASA’s Marshall Space Flight Center have conducted successful rehearsals of the Instrument Payload activation sequence and the IP routine operations procedures from the Flight Mission Support Center, using the spread system this summer. The team also conducted a face-to-face meeting with the POIC at MSFC to review lessons learned from the rehearsals.
